Police say a northwestern Montana man shot and killed a well-known TV host before assaulting his own wife and turning the gun on himself.

Gregory G. Rodriguez, host of “A Rifleman’s Journal,” was killed by a jealous husband Friday after Wayne Bengston found Rodriguez with his wife at her mother's home in Whitefish. Rodriguez was reportedly in town for business but stopped at the home on Thursday night. It’s not known if the two had a relationship.

Bengston, 41, traveled to his wife’s parents’ home and upon finding Rodriguez and his wife, according to the Christian Post, he flew into a rage and shot the TV host dead. Bengston also beat his wife before taking their 2-year-old son - who was sleeping in the house - and dropping the boy off with relatives.

Law enforcement then found Bengston’s truck 25 miles away, in West Glacier, where he was found dead of a self-inflicted gunshot in a small home.

“It’s pretty much an open-and-closed case. Homicide and suicide,” Whitefish Police Chief Bill Dial told the Associated Press. “I think it was a jealous a jealous husband, but this is all conjecture.”
